This is part of gambling where some are determined to hold their trump cards and get the maximum from them while some are working hard to make others to drop their trump cards.
New comers should be very watchful and understand the situation if they want to gamble but if you are an investor I don’t think it will be a problem for you.
Anyway please do remember we also have a responsibility to protect our market and should not always spread negatives. Our market is less exposed to the foreign markets and rise or fall will mainly depend on our own country characteristics and activities.
