How Leverage-Hungry Traders Are Reshaping Stock Market Structure
Retail investors and quant funds are pouring borrowed money into short-term trades, fundamentally altering how markets move.
The stock market you're trading today looks nothing like the one from a decade ago.

That combination is reshaping price action, volatility patterns, and the very plumbing of how stocks move.
When more players use leverage, small moves get amplified fast. A routine dip can cascade into a margin-call spiral. A squeeze can send a stock screaming higher with no fundamental catalyst.

Understanding that leverage-driven flows are driving intraday moves, not just earnings or macro data, changes how you should read charts and size positions.

The takeaway is simple: the rules of engagement have changed. Markets are faster, more reactive, and more prone to violent reversals than at any point in recent memory. Trade accordingly. Continue reading at MarketWatch.com.
