As we head into 2025, investors are giddy over the market returns of the last two years. As shown, the annual returns, while elevated, have come with only average volatility along the way.

However, while most analysts and investors expect 2025 to be another bullish year, there is always a risk of a more disappointing outcome. This is because unexpected, exogenous events can cause a reversal in earnings expectations. Note the words “unexpected” and “exogenous.” It is often stated that “markets climb a wall of worry” because markets “price in” concerns such as geopolitical, monetary, fiscal, or economic concerns. However, when an event occurs that is entirely unexpected, the markets can rapidly reprice. This is particularly an issue when investors take on excessive portfolio risk due to increased overconfidence from a running bull market.
Such was the topic of an article from ARS Technica:
โThereโs extensive academic literature on the risks faced by investors who are overly confident of their ability to beat the market. They tend to trade more often, even if theyโre losing money doing so. They take on too much debt and donโt diversify their holdings. When the market makes a sudden lurch, they tend to overreact to it. Yet, despite all that evidence, thereโs no hard data on what makes investors overconfident in the first place.โ
As we discussed in โBull Markets & Why We Repeat Our Mistakes:โ
โBehavioral biases that lead to poor investment decision-making is the single largest contributor to underperformance over time. Dalbar defined nine of the irrational investment behavior biases specifically:โ
- Loss Aversion – The fear of loss leads to a withdrawal of capital at the worst possible time, also known as โpanic selling.โ
- Narrow Framing โ Making decisions about one part of the portfolio without considering the effects on the total.
- Anchoring โ The process of remaining focused on what happened previously and not adapting to a changing market.
- Mental Accounting โ Separating the performance of investments mentally to justify success and failure.
- Lack of Diversification โ Believing a portfolio is diversified when it is a highly correlated pool of assets.
- Herdingโ Following what everyone else is doing. This leads to โbuy high/sell low.โ
- Regret โ Not performing a necessary action due to regret over a previous failure.
- Media Response โ The media is biased toward optimism to sell products from advertisers and attract viewers/readership.
- Optimism โ Overly optimistic assumptions lead to rather dramatic reversions when met with reality.
โDuring bull market advances, โherding,โ โlack of diversification,โ and โanchoringโ are the most common problems. These behaviors tend to function together and compound investor mistakes.
โBull markets hide investment mistakes. Bear markets expose them.’โ
As shown, โreversions to meanโ remain one of the most powerful forces in investing.

Such is why our “gardening guide” has more to do with managing your portfolio than you imagine. Over the last decade, behavioral finance has studied investor psychology and identified the repeated behaviors investors make throughout market cycles. As you can probably surmise, investors tend to develop many โbadโ behaviors during bull markets, which are the most significant reasons for underperformance over time.

Why Investing Is Like Gardening
Over the long term, investors’ most prominent mistake is failing to manage investment risk.
Individuals tend to do an excellent job of โbuyingโ stocks. However, they are terrible at โsellingโ them. Of course, since the media only tells you to โbuy,โ such should not be surprising. However, โbuying stocksโ is only one-half of the investment transaction. Unfortunately, individuals tend to โsell stocksโ only after accumulating significant losses. Such is the very nature of the โbuy high, sell lowโ syndrome.
Over the years, I have found that our โgardening guideโ resonates with individuals in managing their portfolio and investment risks.
In the โSpring,โ it is time to till the soil and plant your seeds for your summer crops. Of course, one must water, fertilize, and pull the weeds; otherwise, the garden wonโt grow. As the โSpring turns into Summer,โ itโs time to harvest the gardenโs bounty and rotate crops for the โFallโ cycle. Eventually, even those crops must be harvested before the โWinterโ snows set in.
While many investors are skilled at planting gardens, they often forget to harvest the “bounty” they produce. Of course, if the garden’s production is not harvested, it will rot on the vine. Being a good gardener, or โhaving a green thumb,โ is not a function of โluck,โ but rather carefully planned actions to ensure the garden grows, the bounty gets harvested, and the garden is replanted.
Steps To Follow For A โGreen Thumbโ
Therefore, to have a successful and bountiful garden, we must:
- Prepare the soil (accumulate enough cash to build a properly diversified allocation)
- Plant according to the season (build the allocation based on the current market cycle.)
- Water and fertilize (add cash regularly to the portfolio for buying opportunities)
- Weed (sell losers and laggards; weeds will eventually โchokeโ off the other plants)
- Harvest (take profits regularly; otherwise, โthe bounty rots on the vineโ)
- Plant again according to the season (add new investments at the right time)
Like everything in life, there is a โseasonโ and a โcycle.โ When it comes to the markets, โseasonsโ are dictated by the โtechnical and economic constructs,โ and the โcyclesโ are dictated by โvaluations.โ The seasons are shown in the chart below.

As noted above, the โtechnical and economic constructsโ are warning us that we are late into the โFallโ and โWinterโ is likely approaching. Thus, we are taking action to โtend to our gardenโ now so that we will prepare for the first โcold snapโ of winter (a market reversion or potential recession).
So, what actions should you take to prepare your garden for 2025?
The 2025 “Gardening Guide.”
As noted above, the first step in preparing your portfolio for what happens in 2025 is to clean up the things hindering you.
Step 1) Clean Up Your Portfolio
- Tighten up stop-loss levels to current support levels for each position.
- Hedge portfolios against significant market declines.
- Take profits in positions that have been big winners.
- Sell laggards and losers.
- Raise cash and rebalance portfolios to target weightings.
Notice that nothing says, “Sell everything and go to cash.” Trying to “time the market,” which is a binary decision of being “all in” or “all out,“ is a major contributor to underperformance over the long term.
The next step is to rebalance your portfolio to the allocation that will most likely weather a โcold snap.โ In other words, consider what sectors and markets will improve in whatever economic environment you believe we will experience in 2025.
Step 2) Compare Your Portfolio Allocation To The Model Allocation.
- Determine areas requiring new or increased exposure.
- Calculate how many shares need to be purchased to fill allocation requirements.
- Determine cash requirements to make purchases.
- Re-examine portfolio to rebalance and raise sufficient cash for requirements.
- Determine entry price levels for each new position.
- Evaluate โstop-lossโ levels for each position.
- Establish โsell/profit takingโ levels for each position.
(Note: the primary rule of investing that should NEVER be broken is: โNever invest money without knowing where you are going to sell if you are wrong, and if you are right.โ)
Lastly, with a game plan, it is time to pull the weeds, till the soil, plant seeds, and water it.
Step 3) Have positions ready to execute accordingly, given the proper market set-up. In this case, we are looking for positions that have either a โvalueโ tilt or have pulled back to support and provide a lower-risk entry opportunity.

The Benefits Of Portfolio Management
These actions have TWO specific benefits depending on what happens in the market next year.
- If the market corrects, these actions clear out the โweedsโ and protect capital against a further decline.
- If the market rallies, the portfolio is stable, and new positions can be added to participate in the advance.
As discussed in โPredictions For 2025 Using Valuations,โ there is a wide range of potential outcomes for next year. Much will depend on the Fedโs monetary policy changes and economic and earnings growth rates. In that article, we provide several scenarios, but most importantly, two sets of ranges. The first set of forecasts assumes that Wall Street analysts are correct about forward earnings of $251/share.
“The chart below combines the four potential predictions to show the possible market range for next year. Of course, you can analyze, make valuation assumptions, and derive your targets for next year based on your views. This analysis is an exercise in logic to develop a range of possibilities and probabilities over the next 12 months.”

The second option is based on the understanding that Wall Street analysts always overstate earnings growth, which is revised lower over time.
“While the bullish prediction is possible, that outcome faces many challenges in 2025, given the market already trades at fairly lofty valuations. Even in a โsoft landingโ environment, earnings should weaken, which makes current valuations at 27x earnings more challenging to sustain. Therefore, assuming earnings decline toward their long-term trend, that would suggest current estimates fall to $220/share by the end of 2025. This substantially changes the outlook for stocks, with the most bullish case being 6380, assuming a roughly 4.5% gain versus every other outcome, providing losses ranging from a 2.6% loss to a 20.6% decline.”

No one knows with any certainty how the markets will perform next week, much less over the next several months or an entire year. However, we DO know that not managing โriskโ to hedge against a decline is more detrimental to achieving long-term investment goals.
Conclusion
Tending to your portfolio doesnโt take tremendous effort, and I hope our “Gardening guide” can help. The mistake investors make is assuming that planting a garden today will produce its bounty tomorrow. That is not how portfolio management works. Taking action in your portfolio today may lead to short-term underperformance. However, in the long term, managing the portfolio to mitigate the risk of catastrophic losses will lead to a bountiful garden to support you in retirement.
In the short term, managing risk will provide some drag between your portfolio and the major market index if the market rallies. However, when winterโs next โcold snapโ sweeps the markets, preparation should protect your garden from โfrostbite.โ
