Most Retail Investors Don't Read Charts — They Read the Room

Ask a professional trader how they decide to buy a stock and they’ll talk about moving averages, RSI, support levels, and earnings multiples.

Ask most everyday investors? They’ll tell you they saw people talking about it on Reddit. Or a YouTuber they follow was excited about it. Or their group chat was buzzing.

This isn’t a flaw. It’s just reality — and the data backs it up.

The Research Is Clear

A 2024 study published in the International Review of Financial Analysis found that retail investor decisions are more likely to be driven by emotional responses to social media posts than by analyst recommendations. Not sometimes. More likely.

Fresh research from the FINRA Investor Education Foundation — published just weeks ago in April 2026 — found that 60% of investors aged 18–34 use social media to inform their investment decisions. Among that group, 61% had made an investment based directly on a recommendation from a social media personality.

The Ontario Securities Commission found that finfluencer content “significantly influences retail investors’ attitudes and financial decisions” — and that even investors who viewed finfluencers as self-interested still trusted and acted on what they said.

This isn’t a niche trend. It’s how a generation of investors actually operates.

Why Social Beats Charts for Most People

Technical analysis takes years to learn properly. Candlestick patterns, Fibonacci retracements, volume profiles — these require time, tools, and a willingness to be wrong a lot while you learn.

Social media gives you something faster: a read on the room.

When a stock starts getting mentioned repeatedly across Reddit threads, when YouTube comment sections light up with excitement, when the tone shifts from skeptical to bullish — that’s information. Real, human, unfiltered information about how people feel about a stock right now.

And feelings move markets. Especially in the short term.

As one academic analysis put it, Reddit’s WallStreetBets and similar communities drive what researchers call herd behavior — where stock prices rise or fall not because of fundamentals, but because of shared sentiment, fear, or optimism spreading through a crowd.

GameStop in 2021 wasn’t driven by a chart pattern. It was driven by a community that collectively decided to act. The sentiment came first. The price followed.

The Problem With Doing This Manually

Here’s the issue: social media is noisy. For every genuine insight in a Reddit thread, there are ten posts that are emotional, uninformed, or worse — deliberately misleading.

Most retail investors don’t have the time to scroll through hundreds of comments across Reddit, YouTube, and X for every stock they’re watching. And even if they did, separating signal from noise is genuinely hard.

That’s where Senti comes in.

Senti pulls the most engaged posts about a stock from Reddit and YouTube over the past 24 hours — the posts people are actually reading and reacting to — and runs them through AI to produce a single sentiment score from 0 to 10. Bearish to bullish.

You get the read on the room without the hours of scrolling. And unlike traditional financial media, Reddit and YouTube aren’t shaped by advertiser relationships or access journalism. The crowd says what it actually thinks.

A Word of Caution

Social sentiment is a powerful signal, but it’s not the whole picture. The same FINRA research that highlights social media’s influence also notes a knowledge-confidence gap — many social-media-driven investors rate their knowledge highly but score poorly on objective financial knowledge tests.

Sentiment can create momentum. But momentum can reverse. The most effective approach is to use social sentiment as one input among several — not as a replacement for understanding what a company actually does or what it’s worth.

Senti is built with this in mind. The score tells you what the crowd thinks. What you do with that is still up to you.

The Bottom Line

Most retail investors have always made decisions based on what other people are saying — at barbecues, in forums, in comment sections. Social media just scaled that up dramatically.

That’s not going to change. If anything, it’s accelerating. The question is whether you’re reading the sentiment clearly, or just reacting to the loudest voices.

Senti is built to help you do the former.

Senti is a social sentiment analysis app for retail investors. Available on Android, with iOS coming soon. Track stock sentiment across 38,000 tickers at getsenti.ai.
