Should I tax harvesting Tata elxsi and not buy it back?

I bought the stock when it's was 1500 and some at 5000 and already did tax harvesting with it once. Now, even th4 fundamentals remain the same. They don't seem to move forward in price normally any business which is concern. I feel my time is up with the stock and I should sell it and buy different stock with that price. Is it a right decision?
