Never chase stocks just because its share price has fallen steeply.
Telekom Malaysia (TM, 4863) is a publicly listed telecommunications company on the Malaysian stock exchange.
From RM5.00 on 8 May 2018, it has fallen remarkably to RM 2.37 as of yesterday. (Refer to the above screenshot of Google Finance chart)
TM's stock price has been pummeled by the newly-elected government's efforts in fulfilling its manifesto of reducing sky high internet prices. Internet is to be made more affordable, hence the reduction in price of internet packages provided by TM as ordered by the government. Investors fear that TM would lose its monopoly on the fibre broadband market, which in turn would drastically reduce its future profits.
When stocks are on a confirmed downtrend, DO NOT BUY NO MATTER HOW CHEAP IT SEEMS initially, especially where a company loses its competitive advantage. In TM's case, its long-time near-monopoly in the internet segment. Unless you are willing to hold for the long term, your money is better invested elsewhere for a chance of a better gain in the space of a few months.
