Stock selection is a topic that could fill a library, but I want to focus on my small corner of it, which is buying pullbacks.
Investors are drawn to stocks that are pulling back. The logic seems obvious. If a stock was worth $133 two months ago and is now worth $55, it must be a bargain. AST SpaceMobile (ASTS) did exactly that recently, and the buyers who see that decline are convinced they are being offered a discount.
That thinking is flawed, and the flaw costs people more money than almost any other mistake in trading. A lower price is not a bargain. It is just a lower price. Whether it is an opportunity depends on why the stock fell, what your time frame is, and whether you have the discipline to buy it correctly. Those three things are what this discussion is about.
Not All Pullbacks Are the Same Animal
The first step is to define what we are actually dealing with, because the word “pullback” covers two situations that have almost nothing in common.
A stock that drifts down 8% or 10% from a recent high while holding its key moving averages is experiencing normal volatility. Nothing about the trend has changed. The buyers who have been supporting the stock are still there, and the pullback is the market shaking out weak hands and offering a better entry to patient ones. These pullbacks are routine, healthy, and generally safe to buy.
A stock that has been cut in half is a different animal entirely. That is not a pullback. That is technical destruction. The uptrend is gone, the support levels are broken, everyone who bought in the past several months is sitting on a loss, and every bounce runs into sellers who are desperate to get out closer to even. The supply of trapped stockholders overhead is enormous, and it takes months of repair work before a stock like that can sustain a real uptrend again.
Treating these two situations the same way is how traders get hurt. The first one can be bought with reasonable confidence. The second one requires a completely different approach, and usually the best approach is to wait.
Your Time Frame Determines Everything
Before buying any pullback, answer one question honestly: Are you looking for a quick trade or building a longer-term position?
If you are trading, the pullback itself is the setup. You are buying the dip with a defined exit, you expect to be out in days, and you honor your stop if the bounce does not come. The fundamentals barely matter. The trade either works quickly or you are gone.
If you are building a position, the calculation changes. Now the question is not whether the stock bounces this week but whether the decline has changed the longer-term picture. And this is where you have time on your side. A position builder does not need to catch the low. He needs to accumulate good stock at good prices over time, which means there is no reason to rush and every reason to let the chart prove itself before committing serious capital.
Most of the damage I see comes from people mixing the two. They enter as traders, the trade goes against them, and they suddenly discover they are long-term investors. The position was never sized or planned for that, and the eventual capitulation sale is where the real loss happens.
When Fundamentals Blind You to the Chart
In many cases investors let their view of fundamentals and valuation drive their actions more than the chart. They are so excited about buying a great company at a lower price that they pay no attention to the technical conditions. That is when the most costly mistakes occur.
The problem is that your opinion of the fundamentals is just an opinion, and the chart is telling you what everyone else’s opinion is. When a stock is in a clear downtrend, the market is saying that plenty of people with plenty of information disagree with your bullish view, or are being forced to sell regardless of their view. Maybe you are right and they are wrong. But the falling price means you do not need to make that bet yet. The stock is not running away from you. Buying aggressively into a downtrend because the valuation looks attractive is a statement that you know better than the entire market about timing, and that is a statement very few people can back up.
The cheap stock that keeps getting cheaper is one of the oldest traps in the market. Valuation tells you what a stock might be worth eventually. It tells you nothing about what it will trade at next month.
Incremental Is the Only Way
My best advice for buying any pullback, whether it is routine volatility or a broken chart you want to speculate on, is to move incrementally.
I have written it many times and I am writing it again: The mistake that undermines traders and investors more than anything else is averaging aggressively into a falling stock and then panic selling when the bounce never comes. Nearly every experienced trader will tell you their most painful losses followed exactly that script. They were convinced the stock was a good one, they saw the dip as a gift, and they kept buying as it fell. The reality was that something fundamental had changed, or they were simply wrong, and by the time they accepted it they were so heavy that the only option left was selling into the hole.
Buying incrementally solves this. Small initial buys mean a further decline is an opportunity rather than a crisis. You stay in the position I described a few weeks ago, where you want a pullback rather than curse it. And if the stock keeps falling and the story deteriorates, walking away from a small position is easy. Walking away from an oversized one is nearly impossible, which is why people do not do it, which is why they end up riding disasters all the way down.
Broken Stocks Do Not Go Straight Back Up
The recent breakdowns in the technology sector have put all of this on display. Some of the most popular names in the market have suffered severe technical damage, and I am surprised at how anxious people are to buy stocks that are in clear downtrends. They are desperate to catch the exact low, and they seem convinced that these stocks will go straight back up to their old highs.
That is seldom how it happens. Broken stocks bounce, and the bounces can be sharp, but sustainable uptrends take time to rebuild. The trapped sellers have to be worked through. The base has to form. The moving averages have to catch up and turn. The process takes months, not days, and the traders who insist on being first are usually the ones who fund the repair work with their losses.
There is no prize for catching the exact bottom. The prize is buying a stock that is actually going up. Let the broken names prove themselves, keep your buys small while they do, and remember that it is better to be late to the party than early.
