Every investor wants to buy at the lowest point. The idea of entering when pessimism peaks and then riding a big rise is very tempting. In reality, trying to guess the exact bottom can cause big losses.
William O’Neil, the founder of Investor’s Business Daily, says you should look for signs that an uptrend has already started, not try to predict the bottom.
The key idea is the “Follow‑Through Day.” This is a simple but strong clue that the market may be moving from a correction to a real recovery. These days happen when fear and negative news dominate, and selling pressure is high.
A Follow‑Through Day usually shows up a few days after a market low. It features a big jump in a major index along with higher trading volume. The volume boost tells us that big institutional investors are stepping back in. Without their support, rallies often fade.
Studies of past market cycles show that about 50‑70% of Follow‑Through Days lead to longer uptrends. While the signal is not perfect, missing it often means staying on the defensive side.
Today’s market offers a clear example. Recent volatility from geopolitical tensions and oil‑price swings has created the kind of uncertainty that appears during corrections. The S&P 500 has shown sharp intraday moves, and sentiment flips quickly with each headline.
It can be tempting to view a steep drop as a buying chance. But until the market steadies and produces a credible Follow‑Through Day, any rally may be short‑lived.
O’Neil’s method changes the goal. Instead of hunting for the lowest price, investors wait for evidence that the market is being accumulated again.
Research shows that the biggest winners are usually bought not at their lowest point, but as they start moving higher from a solid base. Strong companies lead the way. They have good earnings, strong relative strength, and lead their industries.
Investors who succeed over time are those who align themselves with confirmed trends rather than chasing uncertain lows.
