Shares of Nvidia (NVDA) - Get Report  fell 2.42% to $148.19 on Tuesday as Bloomberg reported that SoftBank Group Corp. (SFTBY) is planning to sell its stake in the giant chipmaker given its recent decline.

SoftBank owned roughly 4.4% of Nvidia through its Sb Investment Advisers as of the end of September, according to FactSet, currently worth about $4 billion. SoftBank has not disclosed how much of Nvidia it wants to sell, or even if it will sell its entire stake, according to Bloomberg. 

After several years of outsized stock market gains, shares of Nvidia have hit a wall recently and are down about 23% this year. Fears of slowing demand for chips have hurt not only Nvidia, but the entire semiconductor industry. Nvidia missed estimates on its quarter ended in November, as TheStreet's Jim Cramer had predicted, partly due to slowing demand from cryptocurrency miners. 

Meanwhile, Nvidia insiders have been shedding some of their positions in the company. Insiders have sold 178,000 shares in the last few months, according to FactSet, with CEO Jensen Huang having sold 41,000 shares over that time. 

Bloomberg reported that by May of 2017, Softbank had accrued a $4 billion position in Nvidia, when the stock was trading just below $130 a share.
