Just explain the pros and cons.
To me, educating oneself is how you manage risks. Hindi rin naman niya fully maiintindihan kung hindi sya invested.
Para di rin ganun kalaki ang risk niya, make her invest not more than 10% of her monthly income every month.
tapos short-term target, make her invest for 3 yrs. Consistently.
ayan, pag ganyan pareho rin kayong magkaka feel ano ang stock market investing kasi i-ga-guide mo siya e
Kung bibigyan kita ng numbers, suppose your Mom takes home a net income every month of 20,000.
So 10 % of that is 2,000
In 3 yrs, total investment niya is 2,000 x 12 x 3 = 72,000
Kung ang interest rate na tatanggapin niya as profit ay hindi bababa ng 10%
yung 72k niya ay pwedeng lumaki hanggang around 95k (33%) provided hindi sya nag wiwithdraw at i-rere-invest niya ang profit niya
E hindi lang 10% ang possible profit sa stock market

The above is just illustration, the 33% profit is not guaranteed.
Siguro in 3 yrs gets na nya how stock market investing works.
I suggest buying or selling not more than 2x a month kasi baka naman malugi kayo sa fees (may fee kasi kada transaction). Kaya I am suggesting investing po ha, not day trading.
Imagine if she's going to retire at age 65, that's 12 yrs from now. If okay ang 3-yr investing experience niya above, then she can still invest for 9 more years.

One more thing,
this is all under the assumption na your Mom already has insurance, emergency fund, no utang, has health coverage.
Kasi kung wala pa, unang unang kukuhanan ng pera ay investments--e hindi ganun ka liquid yun. What if down ang market? e di she will be selling shares at a loss. Kaya dapat may emergency fund.
Dapat din magbayad muna ng utang kasi baka talo sa interes
also, investments are subject to estate tax. that also means they will be frozen if anything happens (you know what I mean). Jan pumapasok ang insurance-- dapat your Mom sufficiently covered para naman hindi sayang ang kanyang mga pinagpundaran
