Every earnings season brings the same question: should we hold our stocks overnight or sell before the financial results are released?
It sounds like a straightforward decision, but the reality is more complicated. One earnings announcement can change market sentiment within minutes. A stock can jump sharply after beating expectations, while another can fall despite reporting record revenue and profits.
Personally, I don’t think holding or selling should be an automatic decision. It depends on the quality of the business, its valuation, the expectations already reflected in the share price and how much risk I am willing to take.
1. A good company doesn’t always mean a good earnings reaction
This is something investors sometimes overlook.
The market doesn’t just compare financial results with last quarter. It compares them with what analysts and investors were expecting.
For example, a technology company might report 30% revenue growth and beat its earnings estimates. That sounds impressive, but if investors were expecting 35% growth, the stock could still sell off.
This is particularly important for AI and semiconductor stocks. Expectations are high, and investors are looking beyond current sales. They want to know whether demand is sustainable, whether profit margins can improve and whether heavy investment in AI infrastructure will eventually generate sufficient returns.
Sometimes the problem isn’t that the company is performing badly. It is simply that the market expected too much.
2. Holding overnight requires more than long-term confidence
I understand the argument that long-term investors shouldn’t worry about daily price movements.
However, I would distinguish between a temporary price fluctuation and a genuine change in the company’s fundamentals.
If a business has a strong competitive position, consistent cash flow, manageable debt and a clear growth strategy, I am more comfortable holding through short-term volatility.
But I wouldn’t use the phrase “long-term investment” to justify holding every stock regardless of its financial performance.
If earnings reveal weakening demand, declining margins or increasing debt, I would reassess the investment rather than blindly wait for a recovery.
3. Taking profits before earnings isn’t necessarily bearish
Another approach is to reduce a position before the announcement.
Imagine a stock has already gained 35% over the past few months. Instead of selling everything, an investor could take some profits and keep the remaining shares.
This creates a more balanced position.
If earnings exceed expectations and the stock rallies, there is still an opportunity to benefit. If the stock falls sharply, some gains have already been protected.
I particularly like this approach when a stock has experienced a significant run-up and its valuation leaves little room for disappointment.
There is no need to turn every earnings announcement into an all-or-nothing decision.
4. Don’t buy the dip without understanding why it happened
Having cash ready is useful, but I wouldn’t automatically buy a stock just because it falls after earnings.
There are two very different situations:
• A temporary market overreaction: The company delivers solid results, but investors sell because expectations were too high.
• A genuine deterioration: Revenue growth slows, guidance weakens, margins contract or customers reduce spending.
The first situation could create an opportunity. The second could be a warning that the original investment thesis needs to be reconsidered.
A lower share price doesn’t automatically mean a cheaper valuation.
5. Forward guidance is just as important as reported earnings
I would pay particular attention to management’s comments about the next quarter and full year.
Revenue and EPS tell us what has already happened. Guidance gives investors an indication of what management expects next.
I would also watch:
• Free cash flow and profitability.
• Operating margins and cost pressures.
• Customer demand and order backlogs.
• Capital expenditure requirements.
• Debt levels and future financing needs.
• Whether management’s growth expectations are realistic.
For AI companies, I would especially watch whether enormous investments in data centres, chips and computing infrastructure are translating into commercial returns.
The AI opportunity is significant, but investors still need evidence that spending can turn into sustainable profits.
6. My strategy: Protect capital without missing long-term opportunities
I would approach earnings season differently depending on the type of stock.
For established companies with strong fundamentals, I am more comfortable holding through earnings if the valuation and position size are reasonable.
For stocks that have rallied significantly, I would consider taking partial profits.
For speculative growth stocks with high valuations, I would be more cautious because even a small disappointment can trigger a large correction.
I also prefer keeping some cash available rather than being fully invested. Cash provides flexibility and allows investors to take advantage of opportunities when the market becomes overly pessimistic.
My final thought
I don’t believe the goal should be to predict every overnight movement. Nobody can consistently know how the market will react to an earnings announcement.
The better approach is to understand what we own, know what expectations are already priced in and decide how much downside we can comfortably accept.
I would rather miss part of an overnight rally than risk too much capital chasing a potential earnings surprise.
For me, successful investing isn’t about winning every earnings night. It’s about making decisions that still make sense after the excitement and volatility have passed.
