It was a week for records in the Sixer Market as we saw some sensational performances in the BBL and in the international circuit. While the first Test between India and Australia saw Josh Hazlewood and Pat Cummins star with the pink ball, a certain Daniel Christian's stock price rose by a massive 17%. Courtesy of the second-fastest BBL fifty ever, Christian joined Daniel Sams and Josh Philippe as the only ones to register a 140+ match score in this year's BBL. However, it might come as a surprise that none of them stands out as the Bull in the Sixer Market. In fact, not even the woeful Indian batsmen, who couldn't withstand Australia's quality bowling attack, finish the week as the Bears of the week. As we build towards a cracking line up of cricket, culminating in an action-packed Boxing Day, insight on the best and the worst-performing player stocks over the past week is in order. Walking along the same lines, here's some much-needed insight to kickstart your week with the latest Bulls & Bears Insight!Bull #1: Tim Seifert (New Zealand/Wicket-keeper)Price: 56.80 Sixer Coins, Price Change: +51.28%, Match Score Average: 114.351.28%! That is the percentage by which Tim Seifert's fantasy stocks rose during the last week as he starred for the Kiwis against Pakistan. Twice in three days, Seifert scored a fifty to chase down a target against Pakistan, handing him a match score average of 114.3 in the series. The percentage increase of 51.28% is the highest increase across the two games after Sanju Samson's rapid rise of 53% during the early stages of the IPL. However, Seifert is just getting started at the moment as he has seemingly sealed a place in the T20I side ahead of Colin Munro. Seifert is a naturally attack-minded batsmen who can also hold his own against the spinners. With the next T20 WC being held in India, Seifert should open the batting alongside Martin Guptill for New Zealand. Not to mention that he also adds value with his wicket-keeping skills. With his fantasy stock price reading 56.80 Sixer Coins per Share, Seifert's form and ability should make him a viable option soon!Bear #1: Shaun Marsh (Melbourne Renegades/Batsman)Price: 52.70 Sixer Coins, Price Change: -17.74%, Match Score Average: 10.57After a stunning start to his BBL 2020 campaign, Shaun Marsh and his fantasy stocks have tailed off in the Sixer Market. The southpaw, who was also in the conversation for a Test cap against India, has witnessed a drastic drop in form with only a match score average of 10.57 to show for his efforts. Despite playing both games at relatively high-scoring venues, Marsh succumbed to left-arm pace on both occasions - a trend which could be a cause for concern. However, Marsh is quite experienced in this form and has all the tools to overturn a price change of -17.74% in the coming games. While his form doesn't promise much, his ability and reputation do, making him one of the more sought-after commodities in the Market. If you are looking to splurge on an experienced and consistent performer in the T20 format, look no further than Shaun Marsh and his fantasy stocks, priced at 52.70 Sixer Coins per Share!Bull #2: Ben McDermott (Hobart Hurricanes/Batsman)Price: 55.10 Sixer Coins, Price Change: +28.2%, Match Score Average: 114.67Another consistent performer in the Big Bash League is Ben McDermott, who unlike Shaun Marsh, was at his supreme best for the Hobart Hurricanes. McDermott, who missed the first two games for the Hurricanes, came up with two masterful fifties, one of them earning him a near perfect score as well! Although it is still early days in the tournament, Ben McDermott is the leading run-scorer in the competition with a match score average of 114.67 adding value to his credentials. Over the last week, McDermott's fantasy shareholders have seen an increase of 28.2% - second to only Seifert. With the wicket-keeper batsman batting in the top order and expected to play a big part in the Hurricanes season from here on, his fantasy stocks provide a great opportunity for a potential profit. At 55.10 Sixer Coins, Ben McDermott could further propel his fantasy stocks, something which you wouldn't want to miss out in the upcoming weeks! Bear #2: D'Arcy Short (Hobart Hurricanes/All Rounder)Price: 49.60 Sixer Coins, Price Change: -14.68%, Match Score Average: 19.64Sticking with the Hobart Hurricanes, albeit for our next Bear of the Week, we have D'Arcy Short, who is down by 14.68% over the last week. The BBL superstar is one of the best cricketers and is known for his power-hitting in this league. However, Short hasn't actually got going so far with only one 50+ match score in BBL 2020. Apart from his stellar fifty against the Strikers, there isn't much to show for his efforts. As there is with every bear in the Market, there is a catch. Short, who has scored over 300 runs in every BBL season he has played in, is available for an absolute bargain of 49.60 Sixer Coins. Short is also expected to have a say with the ball as well, providing the complete package if you are a fantasy shareholder. With limited shares available, you definitely wouldn't want to miss out on the D'Arcy Short bandwagon ahead of the resumption of BBL action on Tuesday!As we approach the much-awaited Boxing Day, where fantasy shareholders will pit their wits across FIVE matches, who are you going to buy?
