There are umpteen arguments on the topic of “time the market vs time in market”. I am not going to argue which is better as it really depends on the skill sets and personality of individuals.For me, I chose to stay in the market as I do not closely monitor the counters in my portfolio. I don’t have the time to do that nor do I want to do that.

With the US market going into the red last night, NVCR’s share price popped! The market cheered its positive late-stage data on the Tumor Treating Fields (TTFields) therapy for non-small cell lung cancer. To be honest, I am amazed by how much the price has appreciated over the news.
While I have seen price going up by 20% to 30% in a day for US shares, this is the first time seeing one going up by near to 70% in a day! I am and probably will not be able to catch such share price movements. So to prevent myself from missing such jumps, I decided that it is better for me to stay in market.
For the record, I am still in the red for NVCR and it is one of the smallest position in my portfolio, so what happened has little impact on my portfolio.
