In the word "Something" are both syllables stressed?

[Zoli]

I've noticed that the dictionary.com website shows stress on both syllables for the word "Something," like so: ˈsʌmˌθɪŋ
The first syllable has primary stress and the second syllable has secondary stress.
However, I checked other dictionaries such as the Cambridge, Webster, and Collins and they only show stress on the first syllable for the word "something."
I would be grateful for your opinion. Thank you.

I checked the "Longman Pronunciation" dictionary as well and there is no secondary stress in the word "something." So, I guess only the first syllable is stressed.

The first syllable is more strongly stressed, but the second syllable is not a weak one.
