The chief market strategist at a $1.3 trillion investment firm shares her best piece of investing advice

You play the hand you're dealt.

Those six words sum up Prudential Financial chief market strategist Quincy Krosby's approach to investing.

Too many money managers fall prey to pre-conceived biases and trade on market conditions they want to exist, rather than simply reacting to what's in front of them, according to Krosby.

In an interview with Business Insider, Krosby discussed Amazon's acquisition of Whole Foods, corporate earnings, the broader tech sector, and the so-called Trump trade. She also discussed her most important advice for anyone starting a career in equity fund management.

Here's what Krosby had to say (emphasis ours):

"You invest and trade in the market you have - not in the one you want. In other words, don't envelop yourself in being bullish or bearish. Just be pragmatic and opportunistic. Take advantage of the market you have.

"It doesn't take much to change the tone of the market - comments from Fed officials, from Washington, or from the CEO of a major company. When you have a big event in the market that causes a quick sell-off, that's usually a buying opportunity.

"But what you do worry about is the business cycle. When that starts to slow down, you have to respect it.

"The last piece of advice is: Respect what the credit markets are telling you."
