Shares of Elon Musk’s Tesla Inc. (NASDAQ: TSLA) are up almost 10% in just the past week, bringing the stock’s year-to-date gain to over 66%. That is undoubtedly stellar run for barely more than seven months of work and one that has recently been fueled by news of the company’s plans for its more cost-effective Model 3.

Tesla’s staggering year-to-date ascent is lifting the stock’s profile in the world of exchange traded funds and mutual funds as some active managers are holding significant Tesla stakes in their funds.

“A total of 22 actively managed mutual funds and exchange-traded funds have more than 5 percent of their portfolios in the company, according to Morningstar data,” reports Reuters. “At 19.4 percent of assets, the $2.1-billion Baron Partners fund has the largest individual stake in Tesla, with 19.5 percent of assets, while another Baron fund, the $185-million Baron Focused Growth fund, has the second-largest position with 17.3 percent of assets in the company.”

Tesla has a market value of about $56.7 billion, or about $6 billion more than General Motors (NYSE: GM). Close to 70 ETFs features exposure to Tesla, but many do not feature large weights to the electric vehicle maker. The actively managed ARK’s Industrial Innovation ETF (NYSEARCA: ARKQ) has one of the largest weights to Tesla among all ETF holders of the stock.

“At 10 percent of assets, the $66-million ARK Industrial Innovation ETF has the largest position in Tesla among all exchange-traded funds, according to Morningstar. The actively-managed fund, which aims to buy companies following a theme of disruptive innovation, is up 33.7 percent for the year,” reports Reuters.

The Global X Lithium ETF (NYSEArca: LIT), which has recently been hitting a string of record highs, has a more than 6% weight to Tesla, putting the stock among the ETF’s top five holdings. Helped by Tesla, LIT is up nearly 34% year-to-date.
