I’ve come across the Efficient Market Hypothesis (EMH) a lot lately.
I’m curious if any traders here really implement it in their strategies or if it’s just something talked about in textbooks.
Theory is nice but profit pays the bills.
EMH says everyone has the same info and acts rationally. Anyone who’s traded during major news knows that’s bullshit.
I’ve been making money trading central bank meetings for years. Same patterns every time - EUR goes crazy 2 hours before ECB pressers, then pulls back within 30 minutes after the spike.
If EMH worked, my moving average crossover on GBP/JPY wouldn’t have printed money for 3 years straight. But it did because people don’t change.
The theory ignores reality - traders have different timeframes, risk appetite, and info sources. When algos dump at month end, retail panics and hands you easy entries.
Don’t overthink it. Trade the charts, not what some professor thinks should happen.
EMH says all info is already baked into prices, so you can’t consistently beat the market through analysis.
It’s partly right but not gospel. Big news gets absorbed instantly - I’ve watched EUR/USD jump 50 pips in seconds after ECB drops. But inefficiencies still exist, especially on shorter timeframes.
I don’t follow it religiously. Found patterns that work reliably, like key support/resistance levels institutions actually respect. London open price action has been pretty predictable for years.
Most academic theory falls apart in real trading. Markets run on emotions and algos that create opportunities EMH completely ignores.
Markets are efficient enough that most retail traders lose money but dumb enough that some patterns still work.
EMH works fine for Buffett’s buy-and-hold strategy, but it’s useless for forex scalping.
Currency pairs constantly react to technical levels - that wouldn’t happen if markets were actually efficient.
EMH doesn’t work in real trading. I’ve seen price moves start way before news hits retail traders. GBP/USD often reacts 30 minutes early to BOE announcements because some players know first. The whole theory assumes we all get the same info at the same time - total BS. Market efficiency sounds nice in textbooks, but watch actual high-volume trading and you’ll see it fall apart. Focus on price action and patterns instead of buying into EMH.
EMH works for long-term investing, but daily trading? Not so much. Institutions constantly hit the same support and resistance levels. If markets were truly efficient, this wouldn’t happen. When central banks make announcements, you’ll see predictable patterns for hours afterward. Plus retail traders panic and get greedy all the time, creating obvious gaps that quick traders can jump on.
