Saturday will mark the 10th anniversary of the longest bull market in history.

On March 9, 2009, the S&P 500 closed at 676.53, marking the low point for the worst bear market in stocks since the Great Depression. Since then, the benchmark index has more than quadrupled in value.

The market was extremely oversold a decade ago as the financial crisis created a rare level of panic, David Russell, vice president at TradeStation, the fifth-largest digital-trading platform in the US told Business Insider.

"We haven't had any real problem since then," he said, adding that Greece's default on an IMF loan payment, the UK's Brexit vote, and Federal Reserve's interest-rate hikes didn't impact strong economic fundamentals in the US.

These companies usually have an old-fashioned business model and a high level of debt, according to Russell.

"The society's shopping habits changed but they didn't keep up," he said. "When those businesses started to shrink, its leverage worked in reverse."
