The recently-concluded IPL offered several viable deals in the Sixer Market. While fantasy shareholders banked on the likes of Ishan Kishan and Jasprit Bumrah, who saw increases of more than +40%, there were a few that slid under the radar despite coming up with the goods. One of them was Faf du Plessis, who was at his best once again for CSK in the IPL! Despite the South African coming up with the goods at the top of the order, CSK weren't able to qualify for the playoffs. However, that shouldn't take any shine away from Faf du Plessis' performances, especially at a time when there were a few doubts over his ability and age. Nevertheless, Faf du Plessis is in line to turn up for South Africa against England later this month, which should be the primary focus for potential fantasy shareholders. Walking along the same lines, here's some much-needed insight on Faf and his fantasy stock viability in the Sixer Market!Up by 30% in IPL 2020, Faf shows no signs of slowing down!Despite being on the wrong side of 30, Faf du Plessis has been a consistent performer for South Africa and the other teams he has turned out for in the last few years. In fact, Faf du Plessis has seen an increase in productivity since the 2019 IPL, where a starred with as many as eight 50+ match scores in twelve games. He was able to translate the same form in the ICC World Cup 2019 as well with two 100+ match scores in eight completed games. One key takeaway from these performances is that he rarely has disappointed in the last year or so and has, more often than not, made up for his subpar performances as well.This was the case in this year's IPL as well. Starting the tournament at 41.76 Sixer Coins per Share, Faf du Plessis started off with match scores of 99 and 131 against MI and RR respectively, which made him one of the most in-demand players in the Sixer Market. The crowning moment for Faf came against KXIP, where his second 100+ score earned him an all-time high of 65.44 Sixer Coins per Share! However, Faf did see a slump in form which saw his price drop drastically to 48.48 Sixer Coins towards the end of the tournament. There were doubts over his long term future at this point although none of this really mattered in the end. Faf ended the tournament in fine fashion with two 50+ match scores against KXIP and RCB, silencing his critics and proving that he does make up for lost time! With an IPL fantasy stock price increase of 30.3%, Faf du Plessis was one of the most profitable assets in the Market, which is a testament to his class and ability!Mission T20 2021 for Faf! Can he keep up his good form?Despite Faf du Plessis averaging a match score of 65.01 in the recently concluded IPL, there are questions over the opportunities he will get in the coming season. Although Faf du Plessis is retired from the longest format, he is still a vital cog in the South African T20I side. Also, Faf du Plessis is beginning to embrace the T20I freelancer role with stints in the T20 Blast, PSL and CPL in recent seasons! His experience and ability to play spin and pace equally well allow him to make up for lost ground, which has been clearly evident as well in recent years.Because the next T20 World Cup is being held in India, buying Faf's fantasy stocks for the long haul makes even more sense. Faf du Plessis is one of the best players of spin in the South African set-up, which should hold him in good stead. Also, he has the experience of playing in the IPL, and during a time when lack of cricket and match fitness is an issue, Faf du Plessis has it covered as he plays in the PSL and for South Africa in next few weeks. At 55.30 Sixer Coins per Share, Faf du Plessis's fantasy stocks are someway of his current 28-match high of 65.44. However, with all the signs pointing towards a fruitful few weeks for his fantasy stocks, he could well scale his all-time high again, which would hand a hefty profit for potential shareholders. So why the long wait? Add him to your portfolio before it's too late!
