The past decade's bull market has reaped some handsome rewards for investors, and investors in tech stocks have seen some of the biggest returns.

We're approaching the ten-year anniversary of what many consider the longest bull market in history. On March 9, 2009, the S&P 500 hit a low of 676.53, and -- despite a plunge in December 2018 -- the index has continued its climb, closing at 2,748.93 on Thursday, March 7.

"Coming off of the financial crisis, we've had the most accommodative interest rate policies from the Federal Reserve in the history of our economy," noted Patrick Healey, founder of Caliber Financial Partners.

Within the tech industry, low interest rates over the 10-year period have particularly favored high-growth names such as Netflix or Amazon, he added: "With rates historically low and when there's a recovery, growth names are always going to do better," Healey said.
