Q: Between ATZ & INMD I best just pack everything in and switch to low cost ETF's.
5i Research Answer:
There is nothing wrong with a low-cost ETF strategy. It lowers risks and gets 'market' returns, minus fees. Losses are part of portfolio management. To get higher returns, there will be bad performers. But we still like the 'math', as losers can only go down 100%, and winners can up 10,000%. The key is to avoid big losses, and keep winners as long as possible. ATZ and INMD have disappointed, but their problems are not fatal. It also has $570M cash to survive its downturn. Index ETFs will get market returns, but will never get 'more' than market returns.
