Scorpio Tankers president Robert Bugbee is not blinking.

Two days after splashing out $2.7m in call option contracts on his company's shares, the veteran tanker executive is laying out $448,000 more of his own funds on a longer-term bet.

Scorpio announced at the close of trading on Wednesday that Bugbee had acquired options on 100,000 common shares with a strike price of $15 and an expiration of January 2023.
