What type of stocks would you consider as Core, Growth, Speculative?

I classify my stocks into catergories as such:

1. Value

2. Growth

3. Recovery

4. Dividend

5. Speculation/Trading

For each catergories I would place 2 examples but please exercise due diligence should you be interested to invest into them.

1. Value: Berkshire Hathaway, Coca Cola

2. Growth: salesforce.com, Alibaba

3. Recovery: SATS, Banks

4. Dividend: REITs, Banks

5. Speculation/Trading: Slack Technologies, Fastly

Hello,

Core - Companies im most confident of with good dividend and moat

Growth - Companies i expects to see it grow, be it share price or dividend, but slightly riskier

Speculative - Those i see in forums LOL but definitely will weigh pros and cons (rarely i buy this unless good potential)

I would add undervalued as a category because if a company is undervalued at current price, it can be seen as a growth (in terms of share price), core (in terms of fundamental) and speculative (potential to rise back).
