If there is no company specific news moving the GGP share price then there are a couple of things that I have noticed that can affect it.
Real (inflation adjusted) US interest rates &/or US Dollar down - Gold up = GGP up
Real (inflation adjusted) US interest rates &/or US Dollar up - Gold down = GGP down
GDXJ (junior Gold Miner ETF) that owns shares in GGP
GDXJ ETF down - GGP down
GDXJ ETF up - GGP up
Recently the US dollar has been moving up, which has moved gold & commodities down, which has knocked the GGP share price down. However, the last couple of days the US dollar flattened and moved down slightly, Gold flat/up, GGP flat/up.
If you spend a bit of time learning how all of this is linked and works together, it’s not only interesting, but it helps you understand what’s happening as well as what could happen going forward.
Best of luck out there.
