For years my trading was slow. I would read a good strategy somewhere, watch someone smart explain it on YouTube, hear a name on a morning finance show, and put the trade on. Sometimes it worked. Often enough it did not, or it worked and I closed it too early, or I doubled down at the wrong moment.
The strategies were not the problem. My execution was.
The day I stopped acting on tips, hot takes, and "here is what I would do right now" content, my results changed. Not because I got smarter. Because I finally followed a plan I wrote myself and trusted my gut feel.
The one study worth remembering#
The classic paper is Barber and Odean (2000), Trading Is Hazardous to Your Wealth, in the Journal of Finance. They tracked 66,465 households at a large US discount broker from 1991 to 1996. The clean, well-replicated findings:
- The average household earned a net return of 16.4% while the market returned 17.9%. A gap of about 1.5 percentage points a year.
- The most active 20% earned 11.4% net, while the market returned 17.9%. A gap of 6.5 percentage points a year.
- The least active 20% earned 18.5% net, essentially matching the market. So the spread between the most active and least active was about 7 percentage points a year, entirely from trading behavior.
- Average portfolio turnover ran about 75% a year. More trading tracked directly to worse returns.
Barber and Odean attributed the gap to overconfidence, and 25 years of follow-on work in other countries and other decades keeps finding the same shape.
Do not!#
Do not act on trade calls from any channel, personality, podcast, or social feed. Learn from them, sure. Copy the trade, no. The person on the screen does not know your account size, your tax residency, your existing positions, your buying power, or your risk tolerance. Even a genuinely good call is not sized for you.
Do not open the platform without a written plan. In your head does not count. Entry rule, size, profit target, stop, and adjustment rule, written down. If any of those five is missing, the trade does not happen today.
Do not size positions by conviction. Confidence is not a risk manager. On defined-risk trades keep the worst case to 1-2% of the account. On undefined-risk, size it so a bad overnight gap keeps your drawdown around 5% or less.
Do not chase what just went up. By the time a name is on your feed, the crowd is already there. Barber, Odean and Zhu (2009) showed individual investors buy overwhelmingly from the small set of names in the headlines, and those names tend to underperform after the attention-driven buying passes.
Do not sell winners early and hold losers. This one is a classic. Cutting losses feels harder than it should. Cut them anyway.
Do not react to headlines outside your trading window. If it mattered, it will still matter when you sit down. Notifications are not a strategy.
Do not confuse activity with progress. Doing something feels like control. Most of the time, doing nothing is the trade.
Do!#
Do write your plan when it is easy, and follow it when it is hard. The market gets scary in the exact moments you need the plan most. That is the whole reason it is written down.
Do verify a setup against your own filter first. Whatever your strategy is (index-DCA, dividend, options premium, breakout), it has objective conditions. Check those. Then, if you want, look at the outside opinion. Never the other way around.
Do size for the worst case. A bad overnight gap sounds theoretical until the morning it happens. Size like that morning is next week.
Do keep a pre-trade journal. Write what you think before you open the trade. Thesis, catalyst, risk, exit. When you audit the year, that pre-trade note is what tells you if your plan is working. The outcome alone tells you nothing.
Do accept variance as part of the strategy. A 70% probability-of-profit trade loses 30% of the time. A 60% strategy loses 40% of the time. A losing streak inside those ranges is not a broken plan. It is the plan running normally.
Do use financial media in learning mode, never in reaction mode. Books, podcasts, deep explainers, out-of-market-hours content, all fine, all useful. Real-time trade calls, closing-bell reactions, morning "what would you do right now" segments, close the tab.
Do turn constraints into an advantage. If you live in a time zone where the market opens late (I do, from Dubai), you physically cannot react in real time to every headline. That constraint is a gift. Whatever your version is, use it.
What this actually looks like in practice#
- Same first ten minutes every trading day. Check open positions against management rules. Check the calendar for binary events. Check what new positions the plan allows.
- Open the platform after that check, not before.
- Place trades
- Follow your profit-taking rule.
- Close the platform when the day's work is done. The market does not need your attention to keep working.
That routine is boring. It is meant to be. Boring is what compounds.
Summary#
Don't blindly follow. Do your own homework.
Write your plan when it is easy. Follow it when it is hard. Do the same thing every day. Consistency is key!
