$Tesla(TSLA.US)$ $Teladoc Health(TDOC.US)$ Wood's seven ETFs returned an average of 141% in 2020, helped by gains in companies like Tesla and Teladoc Health. But the poor performance of these funds, which invest mainly in companies that are not yet profitable and have been in slow decline since their peak in February, has raised questions about their prospects in the months and years ahead. Wood urged investors to continue backing Ark's ETF, saying that a long-term, five-year time horizon would be the best way to judge a fund manager's true performance.
