Ben Stokes set the Sixer Market on fire with a scintillating knock of 99, while Kuldeep Yadav suffered another loss in England's stunning win over India on Friday.The English all-rounder was at his supreme best as he scored nearly 55 runs more than what he was expected to score, earning him a match score of 95.70. He could've achieved more if not for a lacklustre bowling performance. However, his fantasy shareholders profited by 8%, while Jonny Bairstow continued his fine form with a match score of 111.21 to show for his efforts. Both Bairstow and Stokes were particularly severe on Krunal Pandya and Kuldeep Yadav as they overshadowed KL Rahul's ton on Friday. Speaking of Kuldeep Yadav, there's a lot of speculation going on over his market viability. The biggest question that arises is if he is worth the investment? Let's find out in the latest Daily Insight!Trading at an all-time low, is Kuldeep stock worth the investment?Before we get to the answer, we'll need to look into what's actually gone wrong with Kuldeep Yadav. Rewind back to February 2019, India were the hot favourites heading into the ICC World Cup 2019. Their main weapon wasn't Virat Kohli or Rohit Sharma. It was, in fact, their spin duo of Yuzvendra Chahal and Kuldeep Yadav. Their ability to create wicket-taking opportunities with the ball handed India the edge in the middle overs. Kuldeep, in particular, was the go-to man with the Chinaman even picking a six-fer in England.However, it has gone downhill from Kuldeep since the IPL 2019. Ever since he found himself at the receiving end of a Moeen Ali onslaught at the Eden Gardens, Kuldeep hasn't been the same. He returned poor figures quite regularly for KKR and team India, which saw him being dropped midway through the World Cup for Ravindra Jadeja.Since the World Cup, Kuldeep has played in only ten ODIs with eleven wickets to show for his efforts. His economy has consistently been on the higher side, much to his fantasy shareholders' disappointment. Although he does have a hat-trick in this period, his match score average reads 42.16.Although with time and the use of analytics, players are improving, Kuldeep genuinely lacks confidence, something he had in abundance leading into IPL 2019. However, he finds himself in an unusual position heading into the upcoming IPL. Kuldeep isn't KKR's first-choice spinner anymore, although there is a catch.With Sunil Narine's form also being a concern and the fact that KKR will play a couple of games in Chennai, Kuldeep could turn up as the second spinner in the side. Alongside a crafty bowler in Varun Chakravarthy, Kuldeep could be relieved of some responsibility and express himself freely, a ploy that could work in his and his fantasy shareholders' favour.At 38.30 Sixer Coins per Share, Kuldeep is a possible steal. However, recent form messes up his chances in the Market. While the skill is there for everyone to see, it might just be a matter of time before he rediscovers his Midas touch. All he may need is some backing in the KKR camp and also in the Sixer Market!
