Juventus shares soared more than 20 per cent on Wednesday after Cristiano Ronaldo's hat-trick saw them see off Atletico Madrid in the Champions League.
The victory on Tuesday night put the Old Lady through to the quarter finals, earning the Italian champions about £9million in additional payments.
The cash would be on top of the £8m the Italian club received for reaching the last 16.
At 0940 GMT, the shares were up 16 percent topping the leader board on the Milan bourse after hitting their highest since late January in early trading. The shares were on track for their best day since October 2013.
"Considering the amount they gain by qualifying for the next round against the odds, it is quite fair," said a trader.
"Plus looking forward, the only obstacle for them might be Barcelona (if they do qualify) or possibly Man City, the other clubs aren't that great."
Juventus are controlled by Exor, the investment holding of Italy's Agnelli family, which owns nearly 64 percent of the team.
Manchester City, Manchester United and Tottenham Hotspur have reached the last eight of the Champions League, along with Ajax and Porto.
The winners of Wednesday night's ties between Barcelona and Lyon, and Bayern Munich and Liverpool will complete the line-up. The draw for the quarter-finals of the Champions League takes place on Friday.
