The GBP will get weaker in front of a Yen backed by equity firms profitable outcomes. The stocks are generally more attractive to buy since they Yen is stronger. These two countries also have lax laws on cryptocurrencies. Stocks in Japan trade under 15 times this year's earnings forecast, and 13 times next years expectation ( Shameen, 2018). I would sell 25% of holdings. As both the Topix and Nikei indicate another drop. In part due to U.S tax policies abroad.
