Title sums it up. I just don't understand how the market treats any news nowadays as always positive, especially with the Iran crisis. I do understand that capex spending is still here, and companies are backed by real revenue and income, I just don't understand the crazy exuberance like the Marvell situation today. My portfolio for example is extremely concentrated and would do horrible in a large correction / crash. I got extremely lucky buying Micron last year, and I also doubled up on Google, and already cashed out on RobinHood but made a nice chunk of change. My other holdings are mostly consumer cyclicals and pharmaceuticals. I'm thinking of either rotating out of MU entirely and buying some gold, keeping some more cash on the side, and diversifying into some less risky companies, or do you think I'd be better off holding Micron and buying some puts on it, and slowly scaling out of it. Also, I'm a university student, so I have a bigger risk appetite than normal; however, I do not want to be foolish and just hold names that are obviously, to an extent, detached from fundamentals.
