QPR are currently bottom of the Premier League and spent over £20m in the January transfer window in an effort to avoid relegation.
In an interview with The Telegraph, Fernandes conceded that the spending is a risk but said that the money being invested is being done so in a sensible way.
"Anyone who says we are gambling then, of course, we are," said Fernandes.
"I'm an accountant, I run businesses. We are sensible with what we are doing. I don't think there is any recklessness there.
"If you analyse it we haven't spent that much money on transfers and as for our wage bill, when I look at other clubs when they put their results out then ours is not too bad and there is now value in the squad."
