I am looking to begin investing some of my money, as I have been fortunate enough thus far to be able to save a decent amount. My trouble is, I don't know how much of it I should invest. I have read a lot of different information about how much of one's savings should be invested, and have stumbled across many rules-of-thumb such as the 100 rule or the 50/20/30 rule, but I don't know how to interpret these in terms of general savings vs. stocks vs. other types of investments. I have also read a lot of information about how younger people should initially invest more, and take higher risk portfolios, because they have more time to wait, eventually garnering the higher reward despite enduring larger fluctuations earlier on.
My personal situation is basically this: I am three-quarters of the way through my bachelor's degree in engineering. I am extremely lucky and grateful that my parents are in such a financial position that they are able to provide me with my education, and so I don't have tuition costs or student loans. My monthly expenses are minimal, mainly just groceries and household stuff. I am in a co-op program, which means every other term I work full time as a software developer. As a result of this, I currently have saved around $70,000.
Once I graduate, I will be paying my own way with regards to rent and any further education I wish to take. I am not sure if I will do a Masters' degree but I haven't ruled it out, so I would need to have funds available to pay for that if I decide to do it.
My parents' investment advisors are willing to take me on as a client under the family account; they just need to know how much I am willing to invest. I already told them I am happy to take on a more high-risk portfolio, due to my age, but based on all of this information, could anyone offer some advice as to how much (percentage-wise) of my current savings I should be investing?
